... Diode Test and Continuity In diode test, there is only one range +2.08 volts. Voltage is developed across the component(s) under test by a test current output from the Fluke 27. Voltages greater than 2. open test leads produce an overload (OL) condition. Negative inputs produce a negative indication (they are not suppressed). In the diode test function S the beeper produces a continuous tone if the input is less than 0 ...

Page 15

... Note There is normally a small residual reading with open test leads in the conductance range. To ensure accurate measurements, connect clean test leads to the Fluke 27, and (with the leads open) read the residual leakage in nanosiemens. Correct subsequent measurements by subtracting the residual from the readings. This can be done automatically using the Relative mode (REL) ...

... If the input equals or exceeds 3000 counts on the range selected, the bar graph displays, an arrow at the far right of the display. If the manual range annunciator (R) is not displayed, the Fluke 27 automatically switches to the next high range if the input exceeds approximately 3260 counts ...

Page 17

... Specific Applications--Nulling The Fluke 27 bar graph is ideal for nulling adjustments adjustment approaches zero, fewer bar graph segments are displayed, then no bar graph segments are displayed. The - annunciator flickers when the input level is within 10 counts to zero ...

... Battery Installation or Replacement A single 9V battery (NEDA 1604, 6F22, or 006P) supplies power to operate the Fluke 27. Referring to Figure 1, use the following procedure to replace the Fluke 27 battery: 1. Turn the rotary switch to OFF, and remove the test leads. 2. Lift the instrument stand on the back of the Fluke 27, then remove the four black 32, Pozi-drive screws from the battery cover ...
